METR Rule-Maker/Agent --> METR System:
METR information approval

Definitions

METR information approval (Information Flow): This flow supports the approval of verified METR information prior to subsequent provision to METR users.

METR Rule-Maker/Agent (Source Physical Object): The 'METR Rule-Maker/Agent' represents the entity that has the legal authority to establish and digitally sign approved METR rules. An agent is the person that enters the electronic version of the rule into the METR system.

METR System (Destination Physical Object): The 'METR System' creates and maintains electronic versions of traffic rules, regulations, ordinances and statutes that have official status and must be understood by all motor vehicle operators and intelligent vehicles that operate at higher automation levels. This system represents multiple authorities that operate at local, regional, state, and national levels and represents organizations that establish, manage, and enact the traffic code. Each electronic rule is approved, signed, and traceable to a specific rule-maker. Rules are independently verified. Any identified or reported rule discrepancies are analyzed, investigated, and addressed.

Interoperability Description
Not Applicable Interoperability ratings don't apply per se to some types of interfaces like human interfaces. These interfaces may still benefit from associated standards (e.g., ergonomic and human factors standards for human interfaces), but the primary motive for these standards is not interoperability.

Security

Information Flow Security
  Confidentiality Integrity Availability
Rating Moderate High Moderate
Basis May have some PII for internal actors in the METR system, which should not be observed as they could be used as part of phishing or related attacks. Rules could be used to guide vehicle behavior, and if incorrect could lead to vehicles breaking actual rules with potentially highly damaging consequences. Updates are probably infrequent so often this flow can be a less than HIGH availability. In cases of high update (e.g., work zones, incidents), it could be HIGH.
